ther objects I of theinvention will be pointed out in the following description and claims. and

illustrated in the accompanying drawings,which maChiIIEAWhiCh is provided, with two sets. of

keys, of which one setis operated to perforate a record to represent letters, and theother-is operated to perforate la record to represent numerals,

chines 'of the type which are adapted to per forate record cards utilize individual cards as the means for receiving the perforations to rep- ,resent -alphabetical and numeral characters.

Such cards ,;have common dimensions and are i sub-divided into card columnsso that each card column may receive one it or. more perforations to represent a charactert "Aplurality of asso-,

ciated charactersjare: represented in a" plurality -ofcardcohrmns which comprise a cardfleld.

According to the Hollerith system of flcharacw tern designation, usually a single hole represents a single character .but in the combinational' designation system, a pluralityof holes are utilized disclose, byway of example lthe principle of the invention andthe best mode, which has been contemplated, of applying that principle. l

The present invention is particularly useful in that form ,01 punching machine wherein the upper deck, for example, is provided to represent both alphabetical and numerical characters and the lower deck is selected to receive perforations representing only numeral characters.

.Where characters are designated in the combinational system, in one system offcharacter desand by the last mentioned system, the representations ofv the characters mayuse iewer index point positlonsmthan is possible in the Hollerith gsystemof character designation. 1

:- 1 The saving in card space resulting from i the adoption of the combinational designationtsys-fl I operation.

tem, has enabled the cards-to; be further subdivided into twocard fleldsywhich are distinct from the card fields containing associated characters, andin the terminology ofthis art are sometimes known as perforation decksrf In the usual form of record card these decks, as ldesignated herein, aretjsuperposed, teach consisti wh Mrforations, are madein these decks, one deck may ing of a plurality ofcardtcolumns.

,would be madeln" one or two index point posii tionsabove those usedi for numerals, thereby overpunchingtthe lower deck, To prevent such misoperations a locking mechanism is rendered .e ifective upon selection of" the lower deck to efiectively lock out the alphabet keys against Thepresent invention may be constructed according to one or more embodiments or modifications and in. thepresent disclosure, threedif- 'ierent locking arrangements are illustrated so as to disclose the wide yariety of constructions which may be adopted,and which would be witht in thespirit of the invention.

I In one of the. embodiments, a 0

position, thealphabet keys are locked, This lock-- ing action is controlled by{the lever which selects v locking bar of a simple V typefis located beneath the key levers and upon itsmovement to an effective locking the lower deck for punching operations, vIn the second embodiment, the locking bar just referred \tois eliminated andflone or more of the punch selecting bars which'are, shifted only by the depression of the alphabet keys areutilized to perform the locking junction. These bars are operrated only}v by the alphabet keys and, obviously,

' by. locking them against-operation uponfthe selection of one deck, such keys may not be depressed. a While this arrangement issomewhat simpler than the first described embodiment, it may be applied only when certain designation positions and alphabetical codes are selected for representing alphabet and numerals, as will be more apparent as the speci fication is understood.

Each of the two embodiments just referred to is of the mechanical type, and in the present disclosure the third embodiment is electrical in nature and construction. An additional feature of the last named,embodimentfincludes an arrangem'ent whereby the locking action may be utilized in connection with the punching opera-.

tions for the upper deck. This arrangement in'- ent application'to M. Maul, Serial No. 270,324, filed-April 27, 1939, now Patent No. 2,210,552, dated August 6, 1940. For this reason only a general description of the construction and operation of the punching machine will be given, and

only in sufiicient detail to understand the co-- ordination of the present improvements. For

, further details-of operationand construction of cludes a control by the card carriage whereby the alphabet keys are locked against operation when such designations are notto occur in oerj tain card columnsof the upper. deck.-

the punching machinefr'eference may be had to the aforementioned patent.

As more fully explained in the patent, the punching machine is designed and arranged for the perforation of two decks of a record card 2| (Fig. 1 andin the upper deck perforations may As has just been described, the invention is disclosed in several modifications which are to be considered as the preferred embodiments'of the modifications and which are shown in the accompanied drawings in which: V, Fig. 1 is a perspective view of the assembled punching machine which is adapted under" control-of rrgigneral'and alphabet'ke'ys to perforate a record card in two separate decks.- I

Figs. 6 and 7 are, respectively, sectional and planviews of the lockingfmechanism constructed 7 according to the second embodiment of the-invention. e

"Fig. 8 is acombined diagrammatic View re- I lating to the second embodimentof the invention and shows the preferred form of codefor rep- I resenting numerals and alphabetical characters. -This view also shows the association of the key levers of the alphabet an'djnurneral keys with the be disposed so'as to designate alphabetical characters and numerals, but when the machine is conditioned for perforating the lower deck the latter is tobe perforated to represent only numerals.

'view also shows'the association of the keylevers 'of the alphabet and'numeraikeys, the punch The punching machine is provided with a single set of punches l6 (Fig.2) which are commonly 'utilized for perforating both decks. These punches may be selectively coordinated with the decks by displacing the punches so that they will be operatively correlatedwith thedesired deck and this selective" coordination is controlled by a deck selecting leverlfi which, as shown'in Fig. 1, is operable exterior of the machine,and may be preliminarily adjusted. to predetermine the deck which'is to be perforated. Theaforemem' tioned punches l6 comprise a single set of six punches and they are carried by'a carriage which consists, primarily, of twomembers designated 7 l8 and"'l9 in Fig.2 and which are interconnected by meansof screws 20. "The member is slidably -mounted 'in grooves of dovetail formation formed in the" machine housing so that the carriage'may' be slidably' mounted and movedforwardly or rearwardly by'the'manipulation of the lever 26. The me'mberlii' also carries a die plate pzur'igz). L

The dividual selection of the punches i6 is punch selecting bars andmakes it more clear by such illustration, the reason why it is possible in somearrangements to employ two of the punch selector bars operated by the alphabet keys for locking the'alphabet'keys against operation.

Figs: 9-and 10 "are" sectional and plan views,

respectively, of the arrangement forming the third "embodiment of'the" invention. As previously described, this embodimentis electrical in construction and 'further includes'the' feature of looking out one-set of keys under control or the punching carriage of the machine.

The present inventionis preferably incorporated in the form ofpunching machine shown it is to be understood that and not restrictive. It should be further under stood that the invention may be applied to other forms of punching machines which are adapted to punch in two different decks; 'andin which the operation of certain'of the keys arelto be prevented when punching operations in one deck are being performed. j I i c The punching machine shown in Figs. 1 and 2 is nlly shownand described in the U. s. Pathe showing'of this machine is merely illustrative "m Fig. 1.

ireylever II will cause it to effected by the operative displacement of punch selector slides 15 whichare slidably adjusted in a punch operating plate (and the displace- 'ment of the slides 15 iseffected bymeans of Bowden wires which areattached-to the selector.

slides I5 and slidein guide tubes 12, best shown "The ends PM the Bowden wires are connected to the extremities" of selector" bars 50. By the lateral displacement of the'selector bar slide 15 will be operatively displaced through the interconnecting Bowden wire, all of which is more fully shown and described in the aforementioned patent.

As best shown in- Fig. 5,'the' representations of the alphabetical characters and the numerals are eifected by perforations in different hole combinations, the numerals being designated by four hole combinations and the alphabetical charac,

ters by six hole combinations. The perforating of the columns of arranged holes is determined by the displaceselector bars 50 in different combina theyear'd in combinationally ment, of V that'when a key is depressed certain bars 50 will be displaced to effect the displacement of the corresponding punch selector slides i5. "This selective displacement of bars 50 is caused by'the depression of the key levers H of I!) (Fig. 1) and, as diagramthe operating keys matically shownin' Fig. 5, 'fthe depression of a coact with inclined camportibnsj! provided on the selector barsifl.
